The way to build for RPMs is almost the same as the ubuntu_instructions. You install the prerequisites, then build the libraries, then build OpenVSP and package it into an RPM.
Here is an example of how to build an RPM on Fedora release 36:
git clone https://github.com/OpenVSP/OpenVSP.git cd OpenVSP sudo dnf install -y cmake libxml2-devel fltk-fluid fltk-devel g++ \ openjpeg-devel glm-devel rpm-build \ cminpack-devel glew-devel swig doxygen graphviz texlive-scheme-basic \ python3-devel conda mkdir buildlibs cd buildlibs cmake -DCMAKE_BUILD_TYPE=Release -DVSP_USE_SYSTEM_LIBXML2=true \ -DVSP_USE_SYSTEM_FLTK=true -DVSP_USE_SYSTEM_GLM=true \ -DVSP_USE_SYSTEM_GLEW=true -DVSP_USE_SYSTEM_CMINPACK=true \ -DVSP_USE_SYSTEM_CPPTEST=false ../Libraries make -j4 cd .. mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release -DVSP_CPACK_GEN=RPM -DVSP_LIBRARY_PATH=`pwd`/../buildlibs ../src make -j4 package ls -l *.rpm
The resulting RPM installs everything into /opt/OpenVSP.
The Python module is installed into /opt/OpenVSP/python, and you need to follow the steps in the README.md file in that directory in order to make use of it. The Python integration has been tested with Fedora 36.
